StartPage-DC Trojan

I've scanned my computer 50 times with McAfee and again 20 times with CW Shredder. They've all found something in the past until last night. Each one says I'm clean. But when I restart my computer I get a McAfee virus alert that I have the StartPage-DC trojan.

I don't use internet explorer but it's loaded on my computer. I use AOL but I've removed that program.

I can't seem to delete internet explorer.

My CPU is running at 100% and all kinds of *.exe's are open and running.
